DLF Series

Data Line EMI Filters

RoHS-konform AEC-Q flag
Our DLF Series data line EMI filters provide common mode and differential mode filtering in a single component. They reduce conducted noise by a factor of 32 from 5 MHz to 300 MHz and pass data frequencies below 200 MHz with minimal attenuation.
  • Common mode and differential mode filtering in a single component
  • Reduce conducted noise by a factor of 32 from 5 MHz to 300 MHz
  • Data frequencies below 200 MHz pass with minimal attenuation
  • Available in 8, 4, 3 and 2 wire versions
  • Meets IEC 695-2-2 needle flame test requirements
  • AEC-Q200 Grade 3 (−40°C to +85°C)

Hinweise
  1. For optional cover add "C" to part number just before the "L": e.g. DLF 8500CL. Not available on 3500, 4000 and 4500 parts.
  2. Frequency at which the differential mode attenuation equals 3 dB.
  3. Inductance is per winding.
  4. DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Interwinding isolation measured for one minute.
